Sized at 28 inches by 8 inches, it uses a 3-wire actuator with an integrated LED indicator to signal open and closed positions at a glance. The bottom-mount actuator configuration suits installations where access from the underside of the duct is preferred. Licensed HVAC technicians install this damper as part of a zoned residential or light commercial system, controlling airflow to individual zones based on thermostat demand.\u003c\/p\u003e\n\u003cp\u003eThis damper fits rectangular duct runs in residential and light commercial forced-air systems where zoning control is required. The two-position operation  -  fully open or fully closed  -  makes it appropriate for standard zone control boards that switch the actuator between 24-volt power states. The LED indicator provides a visible status check during commissioning and service calls without requiring additional test equipment. The bottom-mount actuator position is selected when duct layout or clearance restricts side or top access.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e28 inch by 8 inch rectangular duct size for direct inline installation\u003c\/li\u003e\n  \u003cli\u003eTwo-position operation: fully open or fully closed for standard zone control\u003c\/li\u003e\n  \u003cli\u003e3-wire actuator wiring compatible with common zone control board outputs\u003c\/li\u003e\n  \u003cli\u003eIntegrated LED indicator displays damper position for fast field verification\u003c\/li\u003e\n  \u003cli\u003eBottom-mount actuator placement accommodates restricted duct clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for rectangular duct zoning systems using 3-wire actuator control boards in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician following local mechanical codes and the zone control system manufacturer's wiring diagram. Power down the air handler and de-energize the zone control board before making any wiring connections. The damper is mounted inline in the rectangular duct run and secured to the duct using sheet metal screws; verify the actuator orientation matches the bottom-mount requirement before final fastening. Confirm LED indicator function during system commissioning to validate proper actuator travel and zone board signal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 28 x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Wiring\u003c\/strong\u003e: 3 wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Mount Position\u003c\/strong\u003e: Bottom mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePosition Type\u003c\/strong\u003e: 2 position\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLED Indicator\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IO HVAC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LD-2808-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67949582352690,"sku":"LD-2808-BM","price":259.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87434551ce229afb9558d3baad520579_e86da6c2-d9ce-4c50-bbc2-617030e47ae7.png?v=1791695469","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-2808-bm-rectangular-zone-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
